The ash produced in big boilers is so high in quantity, that to utilize it completely converting into useful product is not always possible. In such conditions ash is required to be dumped in ash pond / ash pits which are usually far away from the plant area. The most efficient method of disposing ash in such cases is by pumping it in form of slurry through cast basalt pipes.
Slurry pumping can be classified in Low / Medium density and High Density depending on the slurry concentration. The carrying medium is always water.
In case of Coal fired boilers DEMECH system requires less water thereby saving water and also needs lesser headroom below the furnace.
Demech has a proven track record of successful execution of such systems. The scope typically comprises of design, supply, erection & commissioning of long distance Ash slurry disposal system.
